淳朴善良的英文可以用 "innocent and kind" 来表示。

"Innocent" 表示无罪的,指的是没有做过坏事或不会诈骗的意思。"Kind" 表示善良的,指的是热心帮助别人或对他人友好的态度。

举几个例子:

She was a sweet, innocent child who always tried to do the right thing. (她是一个甜美、淳朴善良的孩子,总是努力做正确的事。)
His innocent smile won the hearts of everyone he met. (他淳朴的笑容赢得了他遇到的每个人的心。)
Despite all the hardships she faced, she remained kind and compassionate. (尽管她面临着许多艰辛,但她依然善良和同情。)
